1. Measurement pay-off.
According to the design drawings, the site is measured and the location and elevation of the drainage ditch are determined. At the same time, control piles are arranged on both sides of the trench for subsequent construction.
Second, trench excavation.
The trench excavation is carried out by excavator or manual method, and the excavation width and depth are determined according to the specifications of the drainage ditch and the nature of the soil. The excavation of the trench should be guaranteed to be straight, and there should be no sharp corners to avoid damaging the surface of the drainage ditch.
Third, the cushion is laid.
Lay a certain thickness of cushion at the bottom of the trench, the cushion material can be concrete or gravel, etc., and the function of the cushion is to level the bottom of the ditch and ensure the flatness of the drainage ditch.
Fourth, the installation of drainage ditches.
Place the stainless steel linear gutter on the cushion according to the design requirements to ensure that the gutter is in the correct position and the connection is tight. During installation, avoid leaving scratches or impact dents on the surface of the gutter.
5. Backfill and tamping.
After the installation of the gutter, the backfilling work is carried out. The backfill material should be sand or soil with good permeability, and ensure that the backfill is dense to prevent cavities or settlement.
Sixth, the finishing touch.
Perform a visual inspection of the gutter to ensure that there is no damage and that the joints are tight. At the same time, carry out necessary protective measures for the gutter, such as covering or painting anti-rust paint, etc., to ensure its service life.
The above is the construction practice of stainless steel linear drainage ditch, and the specific operation needs to be adjusted according to the actual situation of the site.
